' 2 Claims. (21. 131-409 This invention relates to improvements in wellpumping devices of the character used for pumping water out of a well inthe ground. and supplying the water to a household pressure system.

When the water in a well contains sulphur or other gases, these areobjectionable in the household water system because of the odor thereofand discoloration resulting from the use of such water in the plumbingsystem, basins, etc. It has been the practice, heretofore, to aeratesuch water as it is pumped from the well so as to allow the separationand removal of the gases.

The system used for aerating. the water and pumping it from the well tothe household pressure system has required the use of two pumps, one ofwhich pumps water from the well into the aerator and asep arate pump tosupply the water from the aerator to the pressure system. Such anarrangement, with separate power operated pumps for the respectivepurposes, not only is expensive to construct and maintain. and operate,but it is ydifiicult to control the relative functions of the pumps, andsuch .a system does not always. function satisfactorily orautomatically. 7 g

One object: in this invention is to overcome the ob jections to wellpumpingsystems usedheretoforeas noted above. g

Another object of the invention is to simplify and improve theconstruction and manner. of operation of well pumping systems of thistype to provide for the operation thereof by means of a single pump asdistinguished from two pumps used heretofore.

Still "another object of the invention is to improve the manner ofcontrolling the system, both as to the filling of the aerator and as tothe supply of water therefrom to the household or pressure system.

According to this invention, a jet is used for drawing the water fromthe well which is supplied and operated by a column of liquid taken fromthe household pressure system, and discharges in to the aerator. Thewater is withdrawn from the latter by the pump and supplied to thepressure system. An electrical control on the pressure side of the jetfunctions in response to the liquid level in the aerator to withdrawwater from the well whenever the aerator becomes low in quantity.

One embodiment of the invention is illustrated in the accompanyingdrawings in which Fig. 1 is a diagrammatic view of the well pumpingsystem as an illustration of this invention, and Fig. 2 is a detailedsectional view of the jet and controls therefor on somewhat largerscale.

The invention is shown as adapted to supply water to a household waterpressure system generally designated by the numeral 1 from a pressuretank 2. This tank 2 contains a body of water maintained under pressureso as to discharge through the line 1 whenever the latteris opened atany valve connected therewith.

Water is supplied to the pressure tank 2 by a pump 3 through a pipe 4extending from the pump to the tank 2. The pump 3 is shown as operatedby an electric 7 2,763,281 Patented. Sept. 18, 19.56

motor 5 supplied with current through wires 6 that are connected withthe electric power line 7. The electric current, including the wires 6,is controlled by a pressure switch 8 mounted in a side of the pressuretank 2 and operating automatically in response to the pressure therein.Theswitch 8: is constructed to close the electric' circuit 6 to themotor 5 whenever the pressure falls to the said low point. Most tanksoperate on a pressure from twenty to forty pounds, in which event theswitch 8 would close the circuit to the motor 5 when the pressure fallsto twenty pounds and would open the circuit to stop the operation of themotor and the pump when the pressure in the tank reaches forty pounds.The setting of these pressures maybe varied as desired.

The pump 3 hasa suction line 9 connected therewith and leading into anaerated tank 10', preferably to a point near the bottom of the latterwhere a foot valve 1'1.is provided. on the lower end of the suction line9' to permit the withdrawal of water from the aerated tank 10' by theoperation of the pump 3. The suction line 9 is shown as extending overthe upper 'edge of the tank 10, although it may be connected in anysuitable manner therewith as desired.

The aerated tank 10 is shown as a receptacle having an open top on whicha cover 12 is supported in upwardly spaced relation from the top of thetank to permit freedom of circulation of air through the upper portionof the latter for aerating the water in the tank and the dischargetherefrom of obnoxious gases.

The water is supplied to the tank 10 through a. filler pipe 13.thatextends inwardly substantially to the center of the tank and has adown-turned open end over a deflector plate 14 mounted in the tank 10,onto which the water is discharged at a point above the liquid level. inthe tank so as to. facilitate the aeration of the water and thedischarge of the obnoxious gases therefrom.

The filler pipe 13 extends inwardly from a jet column 15 shown asmounted externally of the tank 10 and having a jet tube 16. mountedtherein and extending upwardly in the column 15'. I

The lower end of the jet column. 15 is connected with a well pipe 17that extends-downwardly in the well to 'a point below the water leveltherein and usually has a foot valve 18 mounted on the lower end of saidpipe 17. Any suitable well structure may be used as desired forsupplying water to the pumping system and is not illustrated in detail.

A jet is shown at 19 at the lower end of the jet tube 16 in cooperatingrelation with the latter to direct a jet fluid upwardly from the jettube under pressure sufficient to cause a liquid flow through the column15 and into the filler pipe .13, thereby withdrawing water from the wellthrough the pipe 17. The jet 19 is shown as operated by water pressure,having a water line 20 connected therewith and extending thereto fromthe main pressure line 1 of the household system.

The flow of water through the line 20 to the jet 19 is controlled by anelectrically operated valve 21, such as a solenoid valve, controlled bya switch 2-2 mounted at the upper end of the jet column 15. The switch22 preferably is controlled by a float 23 in the aerated tank 10 inresponse to the liquid level in the latter. The valve 21 and switch 22are shown as connected in an electric power circuit generally indicatedat 24 that extends from the power line 7.

The operation of this system will be evident from the foregoingdescription. After the water system is installed, the aerator must firstbe filled to the desired water level therein, preferably more than halffull, before the operation is started. After the first filling of theaerator, the pump may be primed and the cycle will then functionautomatically.

The pressure in the tank 2 being below the minimum set point, the switch8 will be closed, thereby closing the circuit '6 to the motor andoperating the latter as Well as the pump 3. The pump 3 withdraws Waterthrough the suction line 9 from the aerator tank 10 and forces itthrough the pipe 4 into the pressure tank 2, thence to the house line 1.This will continue until the pressure in the tank 2 reaches the maximumset point when the switch 8 will be opened by the pressure in the tank,thereby opening the circuit 6 to the motor and stopping the latter andthe pump.

As water is withdrawn from the tank 10, the water level therein will belowered. This lowering of the water level causes the float 23 to closethe switch 22, thereby closing the circuit 24 to the electricallyoperated valve 21, thus opening the valve. This allows the column ofwater under pressure in the line to be discharged through the jet .19into the jet tube 16 in the form of an injector. This injector acts tolift water from the well through the pipe 17 and the injector tube 15,discharging therefrom through the filler pipe 13 into the tank 10. Thiscycle continues until the float 23 rises sufiiciently to open the switch22 and thereby closing the valve 21.

So long as the water level in the tank 10 is maintained within thedesired range, the injector 15-19 will remain inoperative, but as soon"as the water level lowers su-fficiently, the injector will function towithdraw water from the well into the aerator to maintain a sufiicientquantity therein. This injector functions in response to the pressurebuilt up by the single pump 3 and therefore does not require a separatepump for its operation. The pump operates also automatically in responseto the pressure in the tank 2, being turned on or off automatically asthe pressure varies within the desired range. This cycle continues tomaintain a full supply of aerated water at all times.

The invention has been illustrated and described in one embodiment,although it is realized that variations and changes may be made thereinwithout departing from the invention as set forth in the claims.
